I've had small pain or more like an uncomfortable feeling sometimes in my left testicle for a while. It wasn't too bad so going to the doctor got always prioritized down against other tasks.
Now I discovered that it is somehow collerated to my sex life. I've had about two weeks gap without any orgasms/ejaculation and the pain went away. I did not notice the correlation until I resumed my usual frequent sex life and the pain came back shortly after having frequent orgasms/ejaculation again.
Does anyone have any idea what it could be? It's really starting to worry me but it will be another 2 weeks or so before I'll have time to visit my doctor. I would appreciate any help!

I have the same thing. Urologist explains that it's a varecosel vain. Its a normal problem with a lot of men. Usually it's the left testicle. the left testicle seem to have produced more vains than the right one at birth. This is my understanding/best way to explain it. lol. Anyway, sitting to long, standing to long, or any prolonged activity, sex included can set it off/irritate these vains. surgery is seldom suggested by doctors unless the pain is severe/unbarable to live with. usually, a hot bath with a pain killer does the trick. I notice the problem with my testicle pain in my teens. Some men doesn't start having a problem until later in life. I'm sure your doctor can explain. there is a lot of information on this problem on the internet. Good luck and I hope you start to fealing better!
